Quantitative analysis of single ion species

Abstract

Abstract Method of quantitative analysis of a single ion species paired with at least one species of counter valent ion in an aqueous or highly polar sample solution, the solution containing substantially no other ions of the same valence as said single ion species, save for ions capable of forming a relatively undissociated ion pair with hydrogen ions or hydroxide ions, in which the sample solution is added to an ion exchange resin bed, the resin being an ion exchange resin capable of exchanging ions of the same valence as the at least one species of counter valent ion and the ion exchange resin being in an ion form easily eluted by other ions of the same valence, eluting the single ion species from the ion exchange resin bed and quantitatively detecting the single ion species with a conductivity cell and associated readout means. The apparatus is an ion exchange column charged with an ion exchange resin in an ion form easily elutable by the counter valent ions accompanying a single ion species to be determined, a conductivity cell and associated read-out means, means for bringing sample solution and eluant water to the ion exchange column and liquid conduit means for conducting effluent from the ion exchange column to the conductivity cell.
